DISK CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 603,167, dated Apr126,1898.

Application led November 28,1896. Serial No. 613,758. (No model.)

class described which will be composed of but few parts and be light andstrong and one of such peculiar construction that the disks can' beeasily adjusted bythe driver to' suit the requirements of the occasion.

Having this object in view, the invention consists of a disk cultivatorcomprising those novel features and combinations of pearing more indetail hereinafter;

In the accompanying drawings, Figure 1 is a side elevatiomFig. 2a rearyView, Fig. 3 a plan view, and Fig. 4 a perspective view, of the completemachine,

The draft-tongue. is designated by the numeral 1, and atthe'rea'rof-this draft-tongue there is a drivers seat 2, whilethe machine ismounted on suitable traction-wheels 3.

The numeral 4 designates an adjustmentbox which is in the shape of acasting, connected to the rear portion of the draft-beam underneaththelatter.

5 and 6 indicate two L-shaped frame-pieces or horizontal bars,which havetheir adjacent ends secured in openings or sockets in the opposite endsof the adjustment block or box 4, the arrangement being such as to allowsaid frame-bars to rock in said sockets or openings. When it is desiredto hold the bars at any [ixed adjustment, it is done by means ofsetscreWs 7 and'8,vwhich serve to prevent endwise movement of the`frame-bars, but which when loosened permit the frame-bars to be rockedin rtheir bearing in the adjustmentbox. The pendent rigid arms at theouter ends of these frame-bars extend down through perforations in theboxes 17 and 18, in which the disk-shafts 13 and 14 are journaled, thearrangement being such as to give the shafts a swiveling connection withsaid pendent arms.

parts ap- 9 and l10 indicate pendentl arms intermediate theadjustment-box 4 and the outer rigid arms of the frame-bar and sleevedupon the horizontal portions of said arms or otherwise pivotallyconnected therewith to allow them to swing independently of the rigidpendent arms of said frame-bars. These pendent arms 9 and l10 extendthrough the boxes in which the disk-shafts 13 and-14 are journaled, the

said boxes havinga swiveling connection with 19- and 2O indicatescraper-bars carried by the respective sets of boxes in which the shafts13 and 14 are journaled.

2121 indicate converging rods connected attheir rear ends with the lowerends of the rigid pendent arms of the frame-bars and converging thenceforward, where they pass through a horizontal slot in the tongueindicated at 22. The tongue is also provided with a guide-slot 23.

The numeral 24 designates a cross-beam which has a pivot-bolt 25, thatpasses through the slot in the tongue and is adapted to move therein. Itis not clamped at any point, so it will be seen that this beam has anadjustable pivot-that is to say, the beam can be moved longitudinally inrelation to the tongue and yet at all times be pivoted so that it mayswing horizontally.

The lnumeral 26 designates a rearwardlyextending shifting lever whichhas its forward end rigidly connected to the crossbeam, and this leverhas a dog adapted to ride on and engage with a transverse rack 27,whereby the lever may be locked.

The numeral 28 designates a controllinglever of ordinary construction,which is pivoted to that portion of the rod 21 that is journaled in theframe'and has its lower extremity pivoted to the tongue. Thiscontrollinglever is connected to the cross-beam.

The numerals 29 and 30 designate rods which connect the ends of thecross-beam with the lower portion of the supplemental frame-pieces.

At 3l there is shown a foot-rest for the driver, which can be raised orlowered, as desirable.

The operation is extremely simple and as follows: When it is desired togive inclination to the cult-ivator-disks, the shifting lever can bemoved and said disks and their shafts will be inclined to any desireddegree, as the lever can be locked at any point. If it is desired toraise and lower the disk-shaft and disks, the controlling-lever can bemoved either forwardly or baekwardly, as the case may be, therebyrocking the horizontal arms of the L-shaped frame-pieces in theirsockets in the block or ad justment-box by the simultaneous forward orbackward movement of both the rigid and the swinging pendent arms of thedisk-supporting frame.

Having thus described the invention, what is claimed as new isl. In awheeled disk cultivator, the combination with the draft-beam, of thedisk-supporting frames pivotally connected therewith and having each apendent rigid arm and a pendent arm, adapted to swing on the horizontalframe-arm the disk-shafts having a swiveling connection with said arms,an adjustable cross-bar connected with the pendent swinging arms forsimultaneously swinging the disk-shafts on the rigid arms for adjustingthe angle of presentation of the disks, and means for adjusting saidcross-bar longitudinally upon the machine.

2. In a wheeled disk eultivator, the combination with the disk-shaftsand disks carried thereby, of overhanging frames pivoted to swing in avertical plane and having pendent rigid arms pivoted to the disk-shafts,supplemental suspending arms pivotally connected to the disk-shafts andalso pivoted at points in alinement with the pivotal points of thesuspending frames, means for swinging the suspending frames forwardlyand upwardly, and independent means for swinging the supplemental armsindependently of the suspending frames, whereby the disk-shafts can besimultaneously set at any desired inclination to a transverse line.

3. In a disk cultivator, the combination with depending frame-piecesadapted to swing upwardly, of supplemental pivoted members, sets ofcultivator-disks carried by the main frame-pieces and the supplementalmembers, rods connected to the frame-pieces and movable longitudinallyof the machine, a controlling-lever connected to said rods for operatingsaid frame, a pivoted cross-bar, rods connecting the same to thesupplemental members,a shifting lever adapted for lateral movement andto which the controlling-lever is pivoted, and means for locking thesaid shifting lever.

4. In a wheel disk cultivator, the combination with the pendent rigidarm of the supporting-frame pivoted to swing forwardly and upwardly, ofsupplemental members pivoted to the frame-piece and also adapted toswing forwardly and upwardly, disk-shafts pivoted to the frame-piece andto the supplemental members, disks carried by said shafts, a crossbarpivotally connected with and movable longitudinally of the machine, acontrollinglever having its extremity pivoted to the main frame andwhich is also pivoted to the cross-bar, rods connecting the ends of saidcross-bar and the supplemental members, a shifting lever secured to thecross-bar for adjusting the angle thereof, and means for locking saidlever at any desired adjustment.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
